“…In a combustion process, soot oxidation decreases particle size. Garo et al (1990) and Howard (1996) have measured particulates down to 50 nm in diameter. Thus, it remains to relate the predicted particulate formation and growth to the measured particulate size and emissions index (g/kg of fuel) from gas turbine engines and also to determine how jet fuel additives work to decrease the particulate size and number density.…”

“…The most important oxidative agents of soot in flames have been identified to be OH, O and O 2 [8][9][10][11][12][13]. Experimental evidence exists that the NSC model overpredicts the oxidation rate of soot [14] and synthetic chars [15] at temperatures below 1800 K. Although some uncertainty also exists in the soot oxidation model by OH associated with the collision efficiency of OH attack on soot particle and how it varies with temperature [4,9,[11][12][13]16], it seems that there is no direct experimental evidence indicating a similar behaviour of the current OH oxidation model to that of the NSC model at relatively low temperatures.…”

This study explores the effect of the difference in the carbon structure of particles on their reactivity towards O2. Particles with three types of carbon structures were captured in the exhaust of a diesel engine fueled with blends of diesel with 0, 5, and 15 vol % methanol (designated here as M0, M5, and M15). The Raman spectra were used to designate the particles as a high graphitization structure (L1), a secondary graphitization structure (L2), or a low graphitization structure (L3) according to the carbon cluster content, degree of graphitization, and degree of graphite structure disorder. Additional parameters were measured by thermo‐gravimetric analysis, including the conversion rates, activation energies, ignition temperatures, and combustion and burnout characteristic indices of L1, L2, and L3. The results indicate that the particle conversion differed minimally in the low‐temperature region; however, when the temperature rose to 350°C, the conversion of L3 was much higher than that of L1 or L2. The conversion rates of L1, L2, and L3 each showed a single peak, with corresponding temperatures of 452°C, 427°C, and 400°C, respectively. The conversion rate of L3 was significantly higher than that of L1 or L2. The average activation energy of L3 particles was found to be lower than that of L1 particles by 34 kJ/mol. The ignition temperature of L3 particles was found to be lower than that of L1 particles by 82°C. The combustion and burnout characteristic indices were higher for L3 particles than for L1 and L2. © 2015 American Institute of Chemical Engineers Environ Prog, 34: 1063–1071, 2015
